Bassitt (face) was reinstated from the 10-day injured list ahead of Thursday's start against the Mariners, Matt Kawahara of the San Francisco Chronicle reports.
Bassitt will return to game action for the first time since he suffered multiple facial fractures when he was hit by a comebacker Aug. 17. The right-hander didn't make any rehab appearances ahead of his activation, so his pitch count will likely be monitored against Seattle on Thursday.
